very fine sand -- good or bad
A friend of mine procured some white sand for me that is extremely fine. (As an amateur geologist, he thinks it dates back some 10,000 years to a time when Florida was under water, based on its location inland and depth of 4'-8'.)
In any case, it is much finer than the "live sand" in the tank now, and I wondered if such fine sand would cause problems with the organisms in the sand.
Any experiences with such fine sand in a reef tank bed?
